The follow-up to 'The Way of Water' teases a spectacular epic that includes volcano fights, family tragedy and intense action. Fan reactions are over the top: "Yup, another billion to James Cameron."

Box-office sensation "Avatar" is back with a third movie this December, teasing epic family drama and stunning new creatures in the first trailer.

It is also the movie that will feature the first trailer for one of the most anticipated movies of the holiday season, Avatar: Fire and Ash. To preserve the big-screen majesty of the trailer, it won't be released online beforehand and will instead play exclusively before screenings of The Fantastic Four: First Steps.
